However, when making cuts in the conventional film sheet, it is necessary for the operator to cut the cuts using a cutting blade or the like. When sequentially applying the process manually to the film sheet, it depends on the manual work of the operator. Therefore, not only is work efficiency poor, but there is also an expected upper limit to the accuracy of the work. However, there was a problem in that the burden of expenses such as personnel costs and processing costs was large.

[0011] In addition, the cuts in the film sheet are cut in accordance with the seed sowing pattern of agricultural crops, etc. Use a dedicated pushing blade jig equipped with multiple cutting blades corresponding to the cutting mode, and When a worker presses the film sheet one after another, the seeds of the agricultural product are Depending on the type of seeding ridge, the pattern of the cuts covered in the seeding ridge is determined by the pitch between the cuts, the interval between the cuts, and the cuts. There are many cases where the width changes, and in this case, the dedicated pushing blade jig is no longer used. In addition, it is possible to quickly and arbitrarily change the cut pattern in response to the change. There was a problem in that it was difficult to change.

0012 Furthermore, the pressing blade jig that is sequentially pressed against the film sheet has a predetermined cut pattern. However, as mentioned above, it depends on the operator, so there is no economic There is no doubt that the cost burden is large, and the workers are required to perform simple tasks all day long. The problem is that this burden leads to the generation of defective processed products. There was a point.

[0013] The present invention was developed in view of the above circumstances, and is a method for cutting cuts in film sheets. By making it possible to automate the loading process, we can improve the efficiency of the work and reduce human resources. In addition to reducing labor costs and processing costs, we will also increase the variety of agricultural products and growing soil.

[0051] Note that the deflection angle A of the rotating shaft 72 is determined by the gear box 71 and the cutting mechanism support portion. It is configured such that the angle can be freely adjusted at the attachment site of the material 95. .

[0052] Next, the operation of the incision mechanisms 70, 70' configured as described above will be explained from FIG. This will be explained with reference to FIG. 7.

[0053] In FIG. 5, both the score cutting mechanism 70 and the score cutting mechanism 70' are The rotary head is designed to operate synchronously, and the rotary head changes from the state shown in FIG. By rotating the head rotation surface 79 of the blade 73 in the rotation direction R, the rotary blade is attached. The head 74, rotary blade 75, etc. rotate to a substantially horizontal position.

[0054] Further, when the rotary blade mounting head 74, the rotary blade 75, etc. rotate in the rotation direction R, , so that the rotary blade 75 contacts and cuts the set of film sheets 20. As shown in FIG. Rotate and move.

[0055] At this time, each of the set of film sheets 20 cut by the rotary blade 75 has a The cuts 31, 31'... are cut.

[0056] After that, the rotary blade mounting head 74, the rotary blade 75, etc. are further rotated in the rotation direction R. When rotated, the rotary blade mounting head 74 and the rotary blade 75 are attached to the set of film sheets. 20, and as shown in FIG. Moving.

[0057] Accordingly, cuts 31 and 31' are sequentially formed in the gear box 71.

[0058] Cut cuts 31, 31'... into a set of film sheets 20 as described above. The incision mechanisms 70, 70' configured in this manner are attached to the rotary head 73. Adjusting the rotary blade length L of the rotary blade 75 with the blade length adjustment knob 77, and Adjusting the deflection angle A at the attachment site between the box 71 and the cutting mechanism support member 95 etc., it is possible to cut into any shape. Examples of these are shown in Figures 8 to 8. This will be explained with reference to 12.

[0059] Note that each figure shows a part of a set of film sheets 20. do.

[0060] FIG. 8 shows the basic shape in the following explanation, and shows the incision mechanism 70, 70'... is installed in the specified position, when the film sheet is The state in which the cuts 31, 31'... are cut when the cut cutting device 100 is operated is shown below. It shows.

[0061] At this time, the pitch P1 between the first notches is the interval between the deployment of the notches cutting mechanisms 70, 70'... The first cut interval E1 depends on the rotation by the gear box 71. Delivery regarding the rotational speed or delivery direction D of the blade mounting head 74, rotary blade 75, etc. The first cut width W1 depends on the speed, etc., and the first cut width W1 is determined by the rotary blade mounting head 74. It depends on the rotary blade length L of the rotary blade 75 attached to the blade attachment part 78 in the rotary blade.

[0062] Here, what must be kept in mind is that the sending speed with respect to the sending direction D is Accordingly, the gearbox is cut so that the cuts 31, 31'... are parallel to the head rotating surface 79. Determine the deflection angle A at the mounting location of the box 71 and the cutting mechanism support member 95. It is needed.

[0063] Next, in the incision mechanism 70, 70'..., the rotary blade mounting head 74 are alternately removed from the rotating head 73, the pitch between the first cuts P as shown in FIG. The cuts 111, 111'... having a pitch P2 between second cuts that is twice as large as that of 1 are cut. A set of embedded film sheets 110 is formed.

[0064] In addition, in the state shown in FIG. The rotary blade length L of the rotary blade 75 attached to the head 74 is adjusted by adjusting the blade length adjustment knob 77. When adjusted to make it protrude into a long length, the first cut width W1 as shown in FIG. Cuts 121, 121'... having a second cut width W2 that is longer than that are cut. A set of film sheets 120 is formed.

[0065] Furthermore, in the state shown in FIG. The rotational speed by the box 71 or the feeding direction by the sheet tension feeding mechanism 50, etc. When the delivery speed with respect to D is changed to a high speed direction, the first cut is made as shown in FIG. Cuts 131, 131' having a second cut interval E2 wider than the interval E1... A set of film sheets 130 are formed which have been cut into them.

[0066] At this time, the rotational speed or the delivery in the delivery direction D by the gear box 71 While changing the speed etc., the deflection angle A is controlled by the gear box 71 and the cutting mechanism support. It is necessary to adjust the attachment point with the holding member 95, and if this is not done, the above-mentioned The cuts 131, 131'... are obliquely inclined with respect to the head rotating surface 79 of the rotating head 73. It gets cut into.

[0067] However, if the declination angle A is not adjusted in the state shown in FIG. In this case, as shown in FIG. ), a set of filters with oblique cuts 141 and 141' A sheet 140 can be formed.

[0068] Note that each of the cutting conditions and the like can be arbitrarily combined.

[0069] According to the device 100 for cutting into a film sheet configured as described above, the front The first film sheet 21 and the second film sent out from the sheet sending mechanism 40 A set of film sheets 20 having two layers of sheets 22 is fed out, and the sheet tension The sheet is fed in tension and in the feeding direction D according to the feeding mechanism 50, and the sheet is fed in the tension and feeding direction D according to the feeding mechanism 50. The set of film sheets is cut by the incision mechanism 70, 70'... arranged in 50 parts. Cuts 31, 31'... are cut in the sheet 20, and the sheet is further fed from the sheet tension feeding mechanism 50. A set of film sheets 20 in which the cuts 31, 31'... are cut is placed in the sheet. The storage and winding mechanism 60 is separated into a first film sheet 21 and a second film sheet 22. Since the storage and winding is performed separately and independently, the cut 3 in the set of film sheets 20 The cutting steps 1, 31', etc. can be performed continuously and automatically.

[0070] Further, the rotational power generated by the control power mechanism 80 is transmitted to the notch cutting mechanism 7. 0, 70'... is transmitted and supplied to the gear box 71, and the gear box 71 is The rotational power is transmitted to the rotary head 73 and the rotary blade attached to the rotary head 73. By rotating the head 74, the rotation attached to the rotary blade mounting head 74 is rotated. The rotating blade 75 is configured to rotate, and the rotating blade mounting head 74 is configured to rotate. The blade 75 is attached via the blade attachment part 78 and the blade length adjustment knob 77 adjusts the rotary blade length. L and the location where the gear box 71 and the cutting mechanism support member 95 are attached. Since each corner A is adjustable, it is possible to cut the first film sheet 21 etc. The incision form of the incisions 31, 31', etc. to be made is determined depending on the variety of agricultural products and growing soil. It is possible to quickly and arbitrarily respond to seeding patterns caused by such factors.

[0071] Furthermore, the first film sheet 21 and the second film sheet 22 are The film sheet 20 is formed into a set of film sheets 20 as two layers in the film sheet delivery mechanism 40. At the same time, it is sent to the cutting mechanism 70, 70'... Then, cuts 31, 31'... are cut into the set of film sheets 20, and the sheet storage is completed. Since the storage and rolling mechanism 60 performs the storage and rolling, the cut 3 is removed in the same loading process. 1, 31'... are cut into two first film sheets 21 and a second film sheet. It becomes possible to form and process the sheet 22.

[0072] Further, the sheet feeding mechanism 40, the sheet tensioning and feeding mechanism 50, the sheet storage and winding machine The control power mechanism 80 that transmits power to each of the mechanism 60 and the incision mechanism 70 is single. a drive source (drive motor 81) and a transmitter attached to the drive motor 81. The control operation is performed by the chain 82 and the power chains 83, 83', etc. For example, by having multiple drive sources and controlling them synchronously, a set of film sheets 20 can be produced. The structure is simpler than when cuts 31, 31'... are made in the structural material. It is now possible to reduce costs related to can be lowered.

[0073] Note that it is attached to the rotary blade attachment head 74 in the incision mechanism 70 shown in FIG. Although the rotary blade 75 had a single-edged structure with the blade portion on one side, the rotary blade 75 is not limited to this. , a double-edged structure with blades on both sides may be used.

[0074] This means that if the cutting condition of one of the blades deteriorates, for example, the rotary head 7 The gear box 71 adjusts the rotation direction of the rotary head 73 attached to the gearbox 71. Rotate in the opposite direction to the direction indicated by the arrow of the rotation direction R due to At the same time, by changing the deflection angle A of the rotary blade 75 with respect to the rotation axis 75, , it has the advantage that it becomes possible to utilize the other blade part.

[0075] Furthermore, in this example, as shown in FIG. A set of film sheets 20 to be scored by the device 100 is a first film. A multi-layered film sheet 21 and second film sheet 22 is applied. However, the material is not particularly limited to this, and may be a multilayer of three or more layers.

[0076] Further, the set of film sheets 20 is placed in the sheet storage and winding mechanism 60. Separated and independently stored and rolled up by the first storage roller 61 and the second storage roller 62 However, it is necessary to make cuts in a set of three or more film sheets. For example, an appropriate number of storage rollers are provided for each arbitrary number of sheets, and the storage and winding is performed. It's okay.

[Effect of the idea]

The device for making cuts into a film sheet according to the present invention is configured as described above. Therefore, it has the following effects.

[0078] (1) In the device described in claim 1, each mechanism is powered by a control power mechanism. By supplying and controlling, the film sheet is delivered to the sheet feeding mechanism. At the same time, the sheet tension and feeding mechanism increases tension and feeding. The film sheet is then A cut is made in a predetermined part of the sheet, and then the sheet storage and winding mechanism is used to remove the film. A device for making cuts in the film sheet is configured so that the film sheet is accommodated and rolled up. It is.

[0079] Therefore, it is possible to continuously and automatically cut the cuts into the film sheet. As a result, it is possible to improve the efficiency of work related to the process and reduce labor costs and processing costs. It has the excellent effect of being able to

[0080] (2) In the invention described in claim 2, the rotational power from the control power mechanism is supplied to the gearbox, and the rotational power via the gearbox is applied to the rotating head. A rotary blade mounting head attached to the rotary head and having a rotary blade attached thereto is rotatably driven. The incision mechanism is configured so that the film sheets are fed in sequence. The rotation axis direction of the rotary head has a predetermined deviation angle with respect to the feeding direction.

[0081] This is due to the wide variety of agricultural products and the sowing patterns due to the growing soil, etc. Since the cut state of the cut in the film sheet can be adjusted quickly and arbitrarily, In particular, it has the excellent effect of improving work efficiency in dividing the area of agricultural land. have

[0082] (3) In the invention described in claim 3, the film sheet is transported by a sheet feeding machine. A plurality of sheets are wound in a multilayered manner as a set on the roll part of the structure, and the sheet tension is At the same time as sending out the sheets to the feeding mechanism, the plurality of sheets are made into a set by the cutting mechanism. A cut is made in the film sheet, and the cut is sent out from the sheet tensioning and feeding mechanism. The processed film sheets are stored independently by multiple sheet storage and winding mechanisms. The structure is configured so that the engulfment is carried out.

[0083] Therefore, multiple film sheets with cuts are formed in the same cutting process. Because it can be processed, it dramatically improves the efficiency of processing and reduces processing costs. This has the excellent effect of making it possible to achieve the following.
